When I hooked up the wires for injector 1 I didn't make sure pin 32 went to pin 32 and pin 33 went to pin 33 just beause I figured they go to the same place? What i did was hook up pin 32 to pin 33 ans pin 33 to pin 32. Now I have am having second thoughts and I am paranoid. I did the same thing for injector 2 circuit...

My other problem is with pins 3,4,5,6 for the can bus high and low. The MS page says to only connect the wires on the MS ECU side but I got tan rsautosport harness assembled on one side with these wires already attached. They say the relay board side is the side with 5 extra grounds hanging off of it and should they go to engine ground on the relay board or the engine itself? So did they assemble it wrong? Did I get a v3.0 harness? I didnt connect wires 3,4,5,6 just covered them with shrink tubue and left them open on the ecu side instead.

My last question is when I jump xg1 to xg2 for a hall sender do I need to do anything else to the board?

TIA for anybody's help!

Pins 33 and 32 go to the same place.

Are you using the CANBus or SPR terminals for anything?
